CN105685125A - Compound drug for killing root maggot by root-irrigation - Google Patents

Abstract

The invention discloses a compound drug for killing root maggot by root-irrigation. The drug comprises the following components by weight: 2-4 parts of 50 % phoxim missible oil, 8-10 parts of 40% dimethoate missible oil, 1-3 parts of 90% trichlorfon liquid powder, 2-4 parts of ammonia water, 1-3 parts of garlic, 1-3 parts of clove and 1-2 parts of dried orange peel. The drug has simple proportion, and the liquid flows from the core of the cabbage to rhizosphere to ensure the moist soil around the roots; usually 1-2 times of root irrigation can kill root maggots; and the drug is convenient for usage and can effectively kill root maggots. When the cabbage field has root maggot infestation, 90% trichlorfon, 40% dimethoate missible oil, 50% phoxim missible oil are mixed with an extract of garlic, cloves and orange peel for root irrigation; each plant is irrigated with 200 grams of drug liquid, so that the liquid flows from the core of the cabbage to rhizosphere to ensure moist soil around the roots; and usually 1-2 times of root irrigation can kill root maggots.

Description

A kind of for compound pesticide for killing maggots in root-irrigation mode

Technical field

The present invention relates to growing vegetables technical field, particularly relate to a kind of for compound pesticide for killing maggots in root-irrigation mode。

Background technology

Autumn cabbage, in growth course, avoids ground maggot (also known as root maggot) most, and it stings the epidermis of food Chinese cabbage root, causes the pathogenic bacteria in soil to avail oneself of the opportunity to get in, and causes Chinese cabbage to fall side and rots, not only reduces Chinese cabbage yield, and affect the edibility of Chinese cabbage。As prevented and treated not in time, full field can be made to be injured, cause heavy losses to vegetable grower。The ground maggot of autumn cabbage of causing harm is the larva of Radix Raphani fly, for oligophagy insect, the brassicaceous vegetable such as Chinese cabbage and Radix Raphani of mainly causing harm。

All there is for 1 generation every year in Radix Raphani fly, survive the winter in soil with pupa in various places, rest period about 10 months。The Second Year adult emergence period, mainly in early August, till continuing up to late September, in 8 months, the last ten-days period be occurance peak。Adult every day sooner or later or the cloudy day out movable, noon sunlight strong time lie concealed in Chinese cabbage strain shade place motionless。Autumn Climate warm and moist, occurs serious, and rainfall or after pouring water 1 ~ 2 day, adult quantity significantly increased。After adult is unearthed, through about 7 days, just laying eggs in table soil or table soil seam between the peripheral first and second layer of axil of Chinese cabbage strain and around base portion, ovum is larva, about 30 days larval phases through hatching in 4 ~ 7 days。After this larva occurs, first altering the contiguous petiole base of food Pemisetum flaccidum Griseb. and outer leaf around, then moth food dish root, gallery or the hole in bending, when temperature reduces, harm increases the weight of, and easily brings out the generation of soft rot of cabbage。Conventional chemical pesticide, because spraying for many years, causes that ground maggot develops immunity to drugs, and killing effect is bad, in view of this technical problem, it is necessary to occur that a kind of proportioning is simple, make medicinal liquid from heart of a Chinese cabbage stream to rhizosphere around, ensure that root soil moistens, general pouring root 1 ~ 2 time, ground maggot can be killed。With convenient, it is possible to effectively kill the one of ground maggot for compound pesticide for killing maggots in root-irrigation mode。

Summary of the invention

It is an object of the invention to overcome the shortcoming existed in prior art, it is provided that a kind of proportioning is simple, make medicinal liquid from heart of a Chinese cabbage stream to rhizosphere around, it is ensured that root soil moistens, general pouring root 1 ~ 2 time, can kill ground maggot。With convenient, it is possible to effectively kill the one of ground maggot for compound pesticide for killing maggots in root-irrigation mode。

To achieve these goals, the invention provides a kind of for compound pesticide for killing maggots in root-irrigation mode, wherein, including the following component of parts by weight unit:

Phoxim emulsifiable concentrate 2-4 part of 50%, 40% dimethoate emulsifiable concentrate 8-10 part, 90% metrifonate medicinal liquid 1-3 powder, ammonia 2-4 part, Bulbus Allii 1-3 part, Flos Caryophylli 1-3 part, Pericarpium Citri Reticulatae 1-2 part。

Or, including the following component of parts by weight unit:

Phoxim emulsifiable concentrate 2-3 part of 50%, 40% dimethoate emulsifiable concentrate 8-9 part, 90% metrifonate medicinal liquid 1-2 powder, ammonia 2-3 part, Bulbus Allii 1-2 part, Flos Caryophylli 1-2 part, Pericarpium Citri Reticulatae 1-1.5 part。

90% metrifonate medicinal liquid 1-2 powder unit is mass percent concentration

Advantages of the present invention is that proportioning is simple, make medicinal liquid from heart of a Chinese cabbage stream to rhizosphere around, it is ensured that root soil moistens, general pouring root 1 ~ 2 time, can kill ground maggot。With convenient, it is possible to effectively kill ground maggot。When the Chinese cabbage finding field has root maggot to cause harm, available 90% metrifonate, the dimethoate emulsifiable concentrate of 40%, the phoxim emulsifiable concentrate of 50%, the lixiviating solution of mixing Bulbus Allii, Flos Caryophylli and Pericarpium Citri Reticulatae carries out pouring root, every strain perfusion liquid about 200 grams, medicinal liquid from heart of a Chinese cabbage stream to rhizosphere around, ensure that root soil moistens, general pouring root 1 ~ 2 time, ground maggot can be killed

Detailed description of the invention:

For compound pesticide for killing maggots in root-irrigation mode:

1, the phoxim emulsifiable concentrate of 50% 4 parts, 40% dimethoate emulsifiable concentrate 10 parts, 90% metrifonate medicinal liquid 3 powder, ammonia 4 parts, 3 parts of Bulbus Allii, Flos Caryophylli 3 parts, Pericarpium Citri Reticulatae 2 parts。

2, the phoxim emulsifiable concentrate of 50% 2 parts, 40% dimethoate emulsifiable concentrate 8 parts, 90% metrifonate medicinal liquid 1 powder, ammonia 2 parts, 1 part of Bulbus Allii, Flos Caryophylli 1 part, Pericarpium Citri Reticulatae 1 part。
